Halfway Between 54 and 87

When you ask "What number is halfway between 54 and 87?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=54 and Y=87.

Halfway Between Line

To find the number halfway between 54 and 87, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 54 and 87 into our formula, we get:

(54 + 87)/2 = 70.5

Thus, the number halfway between 54 and 87 is 70.5.

To check that our answer is correct, we subtract 54 from 70.5 and subtract 70.5 from 87 and compare the two numbers:

70.5 - 54 = 16.5
87 - 70.5 = 16.5

As you can see, the halfway number is 16.5 higher than 54 and 16.5 lower than 87. Therefore, our halfway between answer of 70.5 above is correct.
